Feedback - muffler design

Recommended Posts

I just posted this in the engineering forum

I'd love some input from you guys.

Maybe we can get Ed to put his skills to work & build some - swap 'em around amongst ourselves for testing & tweaking?:thumbsup:

Simple, I want a "muffler" - not a silencer (ha!), that's light, yet functional and quiet - could be built cheaply, and not just over-priced "bling".

I haven't checked out your other thread but will later.

A few years back Jeekinz was working on a muffler so he may say something.

EditI see in the other thread Jeekinz did say something.

First, why do you want to chop up the KDX silencer? It is a bit heavy, but is very functional. It's super quiet and makes surprisingly good power when mated to any other pipe than the stock KDX boat anchor. The only thing you gain with an aftermarket silencer is slightly improved throttle response, and more noise.

Two strokes don't particularly like chambered mufflers, because they interrupt the wave tuning of the exhaust. A straight-through silencer relies on the absorption of sound waves by the packing, but a chambered muffler reduces sound by bouncing sound waves against each other to cancel them out. But the expansion chamber needs the reverberating sonic pulses to work properly.

Its not a KDX, its a KX.

I was looking into a dual corevof different diameters - not a baffled design.
